If you want to make a living by trading cryptocurrencies, you must understand these eight rules:

1. Don't just look at K-lines for short-term trading; refer to the overall market trends and resonance to determine entry points.

2. Trade with the trend, avoid blindly going against it, and pay attention to signs of trend changes.

3. For short-term trading, choose promising hot coins, and avoid trading without hot topics.

4. Trade according to your plan, resist impulse, and don't be swayed by market fluctuations.

5. View others' opinions objectively, and insist on independent thinking in strategy selection.

6. First determine the trading direction, then choose the coin, ensuring the direction is correct.

7. Choose coins that are rising; don’t speculate on bottom prices or rebound timing.

8. After significant gains or losses, calmly review and optimize your strategy and mindset while remaining in cash.

Trading cryptocurrencies is a process that combines mindset and strategy; following the rules can improve your success rate.
